Keir's tangling with a discontented Left - as per The Sun ? (8)
I believe the answer is:
starlike
'per the sun ?' is the definition.
I can't tell whether this definition defines the answer.
'keir's tangling with a discontented left' is the wordplay.
'tangling with' indicates an anagram (I've seen 'tangle' mean this).
'discontented' suggests removing the centre (the word's contents are removed).
'left' with its centre taken out is 'lt'.
'a'+'lt'='alt'
'keirs' with its letters mixed up with 'alt' gives 'STARLIKE'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for starlike that I've seen before include "bright but quite small?" , "Resembling pointed object" , "celestial body might be?" , "bright, perhaps?" .)
